Alright I'm going to cut to the chase, I just recently put my traxxas back together after taking it apart to learn a little about it I bought a new spark plug and screws to put it back together but now when I start it starts going on its own. and when I use the breaks it shuts off. help?
That issue is related to your clutch spring either being broke or not installed correctly.
clutch spring is probably broke.
So fix that and both problems are fixed?
